Scrub the X-Amz-Security-Token parameter from query strings

What does this MR do?

Adds X-Amz-Security-Token to the list of sensitive query string parameters.

Why was this MR needed?

Because when the docker-machine Gitlab runner fails to pull an image this query parameter is shown in the Pipelines output.

What's the best way to test this MR?

Run the test suite I guess.

Screenshots

It's chill the token is long expired by now.
